CROSS-REFERENCE TO RELATED APPLICATION

This patent application is a continuation of U.S. application Ser. No. 14/046,030 filed Oct. 4, 2013, now allowed, which is herein incorporated by reference in its entirety.

BACKGROUND Technical Field

The present disclosure relates generally to the integration of various networking functions into a single circuit board for a networked system to enable rapid integration and dynamically modifiable output to display devices.

Background

Specialized vehicles, such as armored vehicles, use comprehensive networked systems to enable the rapid “plug and play” of disparate subsystems within the vehicle. These networked systems seek to provide an “any data, any station” environment in which the data from any sensor associated with the vehicle may be output to any display associated with the vehicle—regardless of whether the different sensors or other inputs use standardized operating platforms or proprietary ones. To implement this functionality, these comprehensive networked systems have cobbled together commercial, off-the-shelf components with a few custom components using custom cabling harnesses.

The cobbling together of commercial components as well as custom components impedes production flow, complicates testing during development, and ultimately hinders the speed in which these comprehensive networked systems can reach the market. The design of the different components, as well as their interconnections, hinders efforts to reduce the physical footprint of the comprehensive networked systems within the vehicles. In addition, these systems have typically used active cooling components that have a lower mean-time-before-failure (MTBF) than solid state components. Accordingly, devices, methods, and systems are needed that overcome limitations with respect to the size, functionality, and speed to market for comprehensive networked systems, as well as other disadvantages.

DETAILED DESCRIPTION

While the present disclosure is described herein with reference to illustrative embodiments for particular applications, it should be understood that the disclosure is not so limited. Those skilled in the relevant art(s) will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the disclosure would be of significant utility.

System Overview

FIG. 1 illustrates an exemplary reconfigurable data distribution system 100, according to an embodiment. Exemplary reconfigurable data distribution system 100 is provided for the purpose of illustration and is not limiting of embodiments of the present disclosure. In an embodiment, the system 100 may be a version of an Electronic Keel (EKeel)® system. As shown in FIG. 1, system 100 includes a plurality of inputs 102.1 through 102.n, integrated system 104, and a plurality of displays 106.1 through 106.m. The plurality of inputs 102.1 through 102.n may include temperature sensors, pressure sensors, velocity sensors, data loggers, image sensors, and/or cameras, just to name a few examples.

The inputs 102.1 through 102.n may be mounted on motors or actuators that allow the system to position the inputs 102.1 through 102.n based on prior feedback from data generated by the system or input by a user. The user may be a human. Alternatively, the user may be a computer or software application. In an embodiment, the request may be based on the user's browsing of a particular website, use of a cloud computing service, or some other remote application as will be understood by a person skilled in the relevant art(s). As just one example, inputs 102.1 through 102.n may be mounted externally on an armored vehicle, such as a Mine Resistant Armor Protected (MRAP) vehicle. Other vehicle types relating to land, sea, or air are also with the scope of the present disclosure, as a person skilled in the relevant art(s) would appreciate. The disclosure is also applicable to any environment or application having multiple heterogeneous inputs and outputs. The inputs 102.1 through 102.n provide data wirelessly or via wired connections to the integrated system 104.

The inputs 102.1 through 102.n provide their collected data to the integrated system 104. For example, the inputs 102.1 through 102.n may provide collected data in analog format for processing or routing by the integrated system 104. Alternatively, the collected data may be provided in digital form to the integrated system 104, as will be appreciated by those skilled in the relevant art(s). The integrated system 104 may receive the collected data from any one or more of the inputs 102.1 through 102.n as streams of data, regardless of the operational platform of a particular input. As the data is received, if the data is in analog format, the integrated system 104 may convert it into data packets. In an embodiment, the data packets may be created according to the internet protocol, although other protocols may be used instead as will be recognized by those skilled in the relevant art(s).

In an embodiment, the integrated system 104 may be an integrated computer built on a single circuit board, such as a computer-on-module. In one example, the integrated system 104 may be designed based on the COM Express® specification hosted by the PCI Industrial Computer Manufacturers Group, for example the Type 6 specification. The Type 6 specification includes a pin out definition in the COM Express® specification, which may include up to 24 peripheral component interconnect (PCI) express lanes, 1 PCI Express Graphics (PEG) interface, 4 serial advanced technology attachment (SATA) ports, 1 local area network (LAN) port, 8 universal serial bus (USB) 2.0 ports, 4 USB 3.0 ports, and multiple display interfaces including video graphics adapter (VGA), low-voltage differential signaling (LVDS), PEG, and device driver interface (DDI). As will be recognized by those skilled in the relevant art(s), the Type 6 specification is just one example. Embodiments of the present disclosure may be implemented in other ways that incorporate the features onto a single circuit board with a similar form factor and range of capabilities.

The integrated system 104 may include one or more dedicated peripherals integrated on the same single circuit board to ensure computational reliability and enable additional monitoring and control of the overall system 100. The integrated system 104 may also include a dedicated microprocessor built on the same circuit board as the rest of the system. The dedicated microprocessor, such as dedicated microprocessor 210 that will be discussed in more detail below with respect to FIG. 2A, may be responsible for attaching and managing various peripherals to the system 100.

In an embodiment, the plurality of displays 106.1 through 106.m may be a plurality of touch screen monitors, or a mixture of touch screen and non-touch capable monitors, just to name a few examples. After receiving the data from the plurality of inputs 102.1 through 102.n and performing any necessary or requested processing on the data, the integrated system 104 may route the data some subset of the data, and/or additional data derived from the received data, to one or more of the plurality of displays 106.1 through 106.m. In operation, the system 100) may enable the viewing of any data source, for example any of inputs 102.1 through 102.n, at any display 106.1 through 106.m. The viewable data may be processed first by the integrated system 104, and/or be displayed as the original data (e.g., analog data) from the inputs 102.1 through 102.n.

The integration of the different computational and peripheral elements onto a single circuit board may significantly reduce the size of the overall system 100. Additionally, in an embodiment the system 100's enclosure may be a conformal heat sink design that enables a passively cooled system. In such an embodiment, the use of solid state parts instead of moving parts for cooling may advantageously increase the mean time before failure. Further, the integration of the computational and peripheral elements onto a single circuit board may enhance the production flow, simplify the testing process, and expedite the speed of these devices to market.

Integrated System 104

FIG. 2A illustrates a modular device, such as integrated system 104, according to a first embodiment. The integrated system 104 may include a power supply 208, a dedicated microprocessor 210, a central processing unit (CPU) host 212, a dedicated interface 214, a plurality of interfaces 216 through 218, a video encoder 222, a communication hub 224 and a switch matrix 226, and a multiplexer 228. As will be recognized by those skilled in the relevant art(s), embodiments here are described with the aid of functional building blocks illustrating the implementation of specified functions and relationships thereof. The boundaries of these functional building blocks have been arbitrarily defined for the convenience of the description. Alternate boundaries can be defined so long as the specified functions and relationships are appropriately performed.

In FIG. 2A, inputs 102.1 through 102.n may send and receive data via interfaces 214, 216, and 218. The dedicated interface 214 may be a USB device dedicated to serial communication. In an embodiment, the dedicated interface 214 may specifically be a FT4232 USB hi-speed integrated circuit, produced by Future Technology Devices International, Ltd. of Glasgow. United Kingdom. Other dedicated circuits may instead be used, as will be understood by those skilled in the relevant art(s). In such an embodiment, the dedicated interface 214 may include a controller area network (CAN) bus-based device, two RS232 serial devices, and at least one COM port to enable communication to the dedicated microprocessor 210. This enables a dedicated, uninterrupted command and control scheme for the integrated system 104. As will be recognized by those skilled in the relevant art(s), the dedicated interface 214 may include more or different interfacing devices as those indicated above.

The CAN bus-based device of dedicated interface 214 may be a dedicated CAN controller that operates at or around 500 Kbits/second, although other speeds may be possible as will be recognized by those skilled in the relevant art(s). The CAN controller may communicate via a CAN data bus, for example a CAN 2.0B specification-compliant data bus. Dedicated software for the CAN data bus, as well as for the dedicated COM port, may allow a full J1939 configurable interface for vehicle applications. In an embodiment, the CAN data bus may be used primarily for vehicle data diagnostics and health monitoring.

The two RS232 serial devices of dedicated interface 214 may enable the attachment of additional serial peripheral devices to the integrated system 104. In an embodiment, the two RS232 serial devices are dedicated to the CPU host 212 via the dedicated interface 214. As will be recognized by those skilled in the relevant art(s), fewer or more than two RS232 serial devices may be implemented.

Interfaces 216 and 218 may represent one or more interfaces to one or more corresponding peripheral devices. Although only two interfaces are shown, a person skilled in the relevant art(s) will recognize that additional or fewer interfaces may be implemented for communication with additional or fewer peripheral devices. Interface 216 may be, for example, an Ethernet switch interface. For simplicity of discussion, reference to interface 216 will be with respect to an Ethernet switch interface 216, although other components may be used instead. The Ethernet switch interface 216 may be integrated on the same circuit board as the other circuits within integrated system 104, such as with the backplane, thereby reducing design costs and constraints. Integration of an Ethernet switch removes the necessity of an external Ethernet switch for networking IP-based devices together to the system 100. The Ethernet switch may support various Ethernet speeds, for example a gigabit speed. Other speeds, both faster and slower, are envisioned as will be recognized by those skilled in the relevant art(s).

Interface 218 may be an interface for any other peripheral device input 102.1 through 102.n that provides a data stream to the integrated system 104, for example temperature sensors, pressure sensors, velocity sensors, data loggers, image sensors, and/or cameras. Interfaces 214, 216, and 218 may communicate with the CPU host 212 via signal paths 264, 262, and 260, respectively. Signal paths 264, 262, and 260 may be single traces or buses.

CPU host 212 is the central component of the integrated system 104 and serves as the primary host for all attached peripherals, whether integrated or external to the integrated system 104. As indicated above, the CPU host 212 may be, for example, implemented according to the motherboard standards in the COM Express specification. In one embodiment, the CPU host 212 may be implemented as a Type 6 COM Express board.

The dedicated microprocessor 210 may be responsible for attaching and managing various peripherals to the system 100. In an embodiment, the dedicated microprocessor 210 may manage the programming of the low-level circuitry of the integrated system 104. The dedicated microprocessor 210 may serve as the gateway for enabling two or more integrated systems 104 to connect and share information, for example across a Xlink interface as will be discussed in more detail below with respect to FIGS. 2B and 3. The dedicated microprocessor 210 may send and receive messages with the CPU host 212 via data bus 254.

In an embodiment, the dedicated microprocessor 210 may be based on a Microprocessor without Interlocked Pipeline Stages (MIPS) architecture and programmable using the C programming language. Additionally or alternatively, the dedicated microprocessor 210 may be a specific, non-time-dependent state machine that is deterministic. The code which the dedicated microprocessor 210 executes may, for example, run and execute from a boot loader. This enables expandability when deployed in the field without requiring physical programming.

The CPU host 212 may output data for display at one or more of the plurality of displays 106.1 through 106.m via one or more of communication hub 226 and switch matrix 224. For sake of simplicity, this discussion will refer to communication hub 226 as USB hub 226 and switch matrix 224 as video switch matrix 224. As will be understood by those skilled in the relevant art(s), other types of hubs and matrixes are possible. The USB hub 226 may communicate with the CPU host 212 via USB bus 256. The USB bus 256 may enable the dedicated microprocessor 210 to attach additional USB input devices or output devices to the CPU host 212, depending on how user or situational requirements change over time. In an embodiment, the USB hub 226 may output data to one or more of the plurality of displays 106.1 through 106.m via a multiplexer 228, which receives data signal 266 from the USB hub 226 and outputs USB output signals 270.1 through 270.m to one or more of the displays.

Any USB input may be output to any display 106.1 through 106.m. In an example, the data input from any input from among inputs 102.1 through 102.n may be routed to any display 106.1 through 106.m. The data input is not necessarily only video data. According to embodiments of the present disclosure, any data input may be routed to any data output. In one example, that input may be video data. The input may additionally or alternatively be radar data. LIDAR data, radio data, etc.

The video switch matrix 224 may communicate with the CPU host 212 via video bus 258. The video switch matrix 224 may be a bus matrix that enables the implementation and display of video sources and routing of analog video sources. In an embodiment, the video switch matrix 224 may enable the implementation and display of VGA sources, for example 3 sources. More or fewer sources are possible, as will be recognized by those skilled in the relevant art(s). These sources may be the CPU processor of the CPU host 212, another integrated system 104 discussed with respect to FIG. 2B below, and another that has been ported out to a MIL-Circ header used for displaying of an external source. Using the video switch matrix 224, any video input may be output to any of the plurality of displays 106.1 through 106.m. The video switch matrix 224 determines what to output to each display 106.1 through 106.m. In an embodiment, the video switch matrix 224 is fully digital and integrated, cycling millions of times a second to enable each display to be reconfigurable on-the-fly.

The video bus 258 may be programmable and adjustable. In an embodiment, the video bus 258 may be a keyboard-video-mouse (KVM) style bus. The keyboard and mouse devices may be additional peripherals that may be controlled by the CPU host 212 and/or the dedicated microprocessor 210, as discussed above.

The video switch matrix 224 may also enable the routing of data from a plurality of analog video sources to a plurality of analog outputs, such as one or more of the displays 106.1 through 106.m. In one embodiment, the integrated system 104 may receive up to four analog video inputs, for example as a subset of the plurality of inputs 102.1 through 102.n. As will be recognized by those skilled in the relevant art(s), the integrated system 104 may be capable of receiving more video inputs. As will be discussed with respect to FIG. 2B below, two or more integrated systems 104 may be attached together via one or more data paths, enabling the attachment of additional video sources, such as analog video inputs, for routing to the plurality of displays 106.1 through 106.m.

In an embodiment, the video bus 258 may also route the plurality of analog video inputs to the video encoder 222. The video encoder 222 may be any type of video server that is capable of capturing analog video data and converting the analog signal(s) into digital video streams. The video encoder 222 may be attached to the CPU host 212 and be PCI or PCIe-based. Once analog video data is captured by the video encoder 222, it may be shared digitally throughout the system 100, for example using IP, and displayed on computer monitors instead of only analog monitors via the video switch matrix 224. The video encoder 222 may include one or more analog video inputs, for example received from the video bus 258. In an embodiment, the video encoder 222 may be able to receive up to 4 analog video signals for conversion into digital video streams, although more signals may be converted as will be recognized by those skilled in the relevant art(s).

The video encoder 222 may also include a dedicated processor for encoding analog video data based on a compression format, and for performing video analysis. Alternatively or in addition, some or all of the processing may occur at the CPU host 212 and/or the dedicated microprocessor 210. The video encoder 222 may detect and process various analog formats, including the national television system committee (NTSC) and phase alternating line (PAL) formats. As will be recognized by those skilled in the relevant art(s), other video signal formats may also be used.

The video encoder 222 may also include a dedicated memory for storing the device's operating instructions and for buffering purposes. The video encoder 222 may also include its own dedicated input and output interfaces, for example a dedicated Ethernet port for sending and receiving digital data and/or an RS232 port to assist in controlling the functionality of one or more analog video sources. Additionally or alternatively, the video encoder 222 may use the interfaces 214, 216, and 218 to communicate with one or more of the plurality of inputs 102.1 through 102.n.

In an embodiment, the video bus 258 includes both the VGA and analog video data. In an alternative embodiment, the video bus 258 may be composed of two distinct busses for each of the VGA and analog data respectively.

The power supply 208 may supply the different power needs of all of the devices integrated with integrated system 104. The power supply 208 may receive power input 250, for example from a MIL-STD power interface provided in military vehicles. As will be recognized those skilled in the relevant art(s), the power supply 208 may receive power input 250 from other sources in addition to, or instead of, a MIL-STD power interface in a military vehicle. The power supply 208 will be addressed in more detail below with respect to FIG. 3.

The different components integrated on the same circuit board in integrated system 104 have very short signal paths to each other and particularly to the CPU host 212, which results in a reduction of information loss. The integrated system 104 overall has a small form factor. For example, the integrated system 104 may have a width (x-dimension) of less than 10 inches, such as 9.25 inches, as well as a length (y-dimension) of around 6 inches, and depth (z-dimension) of less than 1 inch, such as 0.093 inches. In one embodiment, the integrated system may have 12 total layers. These are examples only, and one skilled in the relevant art(s) would recognize that other dimensions and combinations are possible without departing from the scope of the present disclosure.

FIG. 2B illustrates a modular device, such as integrated system 104, according to a second embodiment. For sake of simplicity, only those elements that are different from the elements discussed above with respect to FIG. 2A will be addressed. The integrated system 104 of FIG. 2B additionally includes a linking module 220 and a daughter card connector 230.

The linking module 220 may be, for example, an XLink that enables the connecting of two or more integrated systems 104. In an embodiment, the dedicated microprocessors 210 of two integrated systems 104 may share information via the linking module 220. The data from inputs to one integrated system 104 may be routed as connection signal 272 via the linking module 220 to the second integrated system 104 for output at a display connected to the second integrated system, and vice versa. In one example, that data may be analog video data, VGA video data, or data from other video or non-video inputs from among the plurality of inputs 102.1 through 102.n.

In further support of the linking module 220's interface, an Ethernet cable may be attached to the Ethernet switch interface 216 for added bandwidth data sharing between the first integrated system 104 and the second integrated system 104. In embodiments where there are multiple integrated systems 104 connected, for example via linking module 220, the second integrated system 104 may operate to attach one or more peripherals to the first integrated system 104, and vice versa.

Daughter card connector 230 may provide an interface for the integrated system 104 to enable attachment of a daughter card to the integrated system 104 to further improve upon the system 100's dimensions and form factor. In an embodiment, the daughter card connector 230 may enable additional peripheral device(s) to connect via a daughter card so that the additional peripheral device(s) are parallel to the integrated system 104's circuit board, rather than perpendicular.

Power Supply

FIG. 3 provides a diagram illustrating the power supply 208 of an exemplary integrated system 104 according to an exemplary embodiment. The power supply 208 may be a power system customized from the Advanced Technology eXtended (ATX) specification. The power supply 208 may be able to continuously operate off of a range of voltage input values, for example ranging from a 6.5V to a 42V power input 250 and output the standard voltages of 12V, 5V, 3.3V, −5V, and standby 5V and 3.3V. Power input 250, for example from a MIL-STD power interface, may first be filtered by input power filter 302. In an embodiment, input power filter 302 may include a common mode filter that provides noise reduction as well as immunity to the changing power-noise environments in which the integrated system 104 may be found. A first input voltage 352 may be routed to multiple voltage supply circuits, for example a standby power supply 306, CPU host power supply 312, a second supply 314, and a third supply 316.

The standby power supply 306 may receive the first input voltage 352 and output, in response, a first standby voltage 356, a second standby voltage 358, and a standby-good signal 354. In an embodiment, the standby power supply 306 may also be connected to a switch circuit (not shown) that may control a run signal in the standby power supply 306. When the switch circuit is short circuited, or “on,” it may pull the run signal above a minimum voltage, for example 1.2V. When the switch circuit is “off,” the run signal may be at ground. This is reflected in the standby voltages 356 and 358, as will be addressed below. In an embodiment, the first standby voltage may be 3.3V and the second standby voltage 358 may be 5V. Although other voltage values are possible, as will be recognized by one skilled in the relevant art(s), these particular voltage values will be used for sake of simplicity in this discussion. The 5V standby voltage 358 may be output to the rest of the integrated system 104, as well as input into each of the other power supplies 312, 314, and 316, and the power check circuit 320. The 3.3V standby voltage 356 may be output to the rest of the integrated system 104 and input into the power check circuit 320 and the multi-frequency clock 310.

The multi-frequency clock 310 may receive as inputs the 3.3V standby voltage 356 and the standby-good signal 354. The multi-frequency clock 310 is designed to provide multiple clock signals, at the same or different frequencies, to the other circuits within the power supply 208. As will be recognized by those skilled in the relevant art(s), there are many ways to implement the multi-frequency clock 310 which fall within the scope of this disclosure. In an embodiment, the multi-frequency clock 310 outputs clock signals 360.1 through 360.4, although any other number may be output as is understood. The clock signal 360.1 may be output to the CPU host power supply 312. The clock signal 360.2 may be output to the second supply 314, and the clock signal 360.3 may be output to the third supply 316. The clock signal 360.4 may be output to the standby power supply 306. The multi-frequency clock 310 may also provide synchronization, for example to reduce jitter in the clock signals 360.1 through 360.4.

The CPU host power supply 312 may receive as inputs the first voltage input 352, the 5V standby voltage 358, and the clock signal 360.1. The 5V standby voltage 358 may operate as an on/off signal for the CPU host power supply 312, for example corresponding to when the run signal is “on” and “off” The CPU host power supply 312 may provide a first output power voltage 362. The first output power voltage 362 is output to the integrated system 104 for use by other circuits, components, and peripherals, as well as fed to the second supply 314 and the third supply 316. In an embodiment, the first output power voltage 362 may be a 12V power signal, in accordance with the ATX specification. The CPU host power supply 312 may also output a CPU host power supply good signal 372.1 to the power check circuit 320.

The second supply 314 may receive as inputs the first voltage 352, the 5V standby voltage 358, the clock signal 360.2, and the first output power voltage 362. The 5V standby voltage 358 may also operate as an on/off signal for the second supply 314. The second supply 314 may provide a second output power voltage 364, which is output to the integrated system 104 for use by other circuits, components, and peripherals. In an embodiment, the second output power voltage 364 may be a 5V power signal, in accordance with the ATX specification. The second supply 314 may also output a second supply good signal 372.2 to the power check circuit 320.

The third supply 316 may receive as inputs the first voltage 352, the 5V standby voltage 358, the clock signal 360.3, and the first output power voltage 362. The 5V standby voltage 358 may also operate as an on/off signal for the third supply 316. The third supply 316 may provide a third output power voltage 366, which is output to the integrated system 104 for use by other circuits, components, and peripherals, as well as by the low voltage supply 318. In an embodiment, the third output power voltage 366 may be a 3.3V power signal, in accordance with the ATX specification. The third supply 316 may also output a third supply good signal 372.3 to the power check circuit 320.

The low voltage supply 318 may receive as input the third output power voltage 366. The low voltage supply 318 may provide the power system support required by different dedicated peripherals in the integrated system 104, for example Ethernet switch interface 216 of FIGS. 2A and 2B. The low voltage supply 318 may output first low voltage 368 and second low voltage 370 to the integrated system 104 for use by the circuits, components, and/or peripherals that require low voltage support. The low voltage supply 318 may also output a fourth supply good signal 372.4 and a fifth supply good signal 372.5 to the power check circuit 320.

The power check circuit 320 may receive as inputs the 3.3V standby voltage 356, the standby-good signal 354, the CPU host power supply good signal 372.1, the second supply good signal 372.2, third supply good signal 372.3, and fourth and fifth supply good signals 372.4 and 372.5. The power check circuit 320 determines whether the outputs of the different supplies within power supply 208 are stable and adequate for use outside of the power supply 208.

In operation, the power supply 208 may continuously operate off of a range of voltage input values, for example ranging from a 6.5V to a 42V power input 250 and output the standard voltages of 12V, 5V, 3.3V, −5V, and standby 5V and 3.3V according to the ATX specification.

Scaled System 400

In FIG. 4, multiple integrated system environment 400 is illustrated, according to an exemplary embodiment. For purposes of discussion, only those elements that differ, or are in addition to, the elements discussed above with respect to FIGS. 2A and 2B will be addressed. Multiple integrated systems 104.1 and 104.2 are shown in FIG. 4, connected together using connection signal 272 which may be a cable or wireless connection, for example. Although two integrated systems 104.1 through 104.2 are shown in FIG. 4, those skilled in the relevant art(s) will recognize more than two may be combined to increase the functionality of the overall multiple integrated system environment 400. The environment 400 may still include the plurality of inputs 102.1 through 102.n, and plurality of displays 106.1 through 106.m.

In an embodiment, the plurality of inputs 102.1 through 102.n are a first plurality of inputs attached to the first integrated system 104.1. A second plurality of inputs 102.o through 102.p may be attached to the second integrated system 104.2. This situation may arise, for example, where there are more inputs than a single integrated system 104 may receive, or where additional processing power is desired. Any from the first plurality of inputs 102.1 through 102.n and the second plurality of inputs 102.o through 102.p may be output to any of the displays 106.1 through 106.m. Although shown in FIG. 4 as being attached to only integrated system 104.1, there may be additional displays attached to integrated system 104.2, and any input may still be output to any display attached to either integrated system.

The combination of multiple integrated systems 104 may significantly improve processing performance while still maintaining a small form factor. Additionally, in an embodiment the integrated systems 104.1 and 104.2 in environment 400 may be enclosed in a conformal heat sink design that enables passive cooling. The integration of the computational and peripheral elements onto a single circuit board in each integrated system 104.1 and 104.2 may enhance the production flow, simplify the testing process, and expedite the speed of these devices to market, as well as add scalability and bandwidth by the combination of multiple integrated systems.

Exemplary Methods

FIG. 5 illustrates a flowchart of method 500, an operation of a video switch matrix, according to an embodiment. For example, the video switch matrix may be video switch matrix 224 of FIGS. 2A and 2B above.

At step 502, the video switch matrix 224 receives a plurality of inputs, for example from inputs 102.1 through 102.n. The plurality of inputs 102.1 through 102.n may be routed to the video switch matrix 224 via the video bus 258, as discussed above.

At step 504, the video switch matrix 224 determines which input from among the plurality of inputs 102.1 through 102.n to route to which of the displays 106.1 through 106.m. The video switch matrix 224 may be reprogrammed many times in a short period of time, for example millions of times in a given second, to enable on-the-fly reconfigurable capabilities to the displays 106.1 through 106.m. As a result, each display 106.1 through 106.m may, from the point of view of a user, immediately change what is displayed based on the constant reprogramming within the video switch matrix 224.

At step 506, the inputs are output to one or more of the displays 106.1 through 106.m via video output signals 268.1 through 268.m. As a result, any input to the integrated system 104 may be output to any display.

FIG. 6 is a flowchart illustrating an operational flow 600 of a modular device, such as integrated system 104, according to an embodiment.

At step 602, the integrated system 104 receives a plurality of inputs, for example from inputs 102.1 through 102.n that have been attached to the integrated system 104.

When the integrated system 104 receives data inputs, the integrated system 104 routes the data internally either in its native format or in a digitized format, for example after conversion by the video encoder 222. This is depicted in steps 604 and 606. At step 604, after the microprocessor 210 has managed the attachment of the peripheral providing the data input, the data may be routed internally in its native format, for example when the data input is an analog video source. If instead the data is to be converted, it is routed to the video encoder 222 and digitized at step 606.

At step 608, whether the integrated system 104 is routing analog or digital data corresponding to the inputs 102.1 through 102.n, the video switch matrix 224 determines which input to route to which display 106.1 through 106.m when the data is video data, as discussed above with respect to FIG. 5. The US hub determines which USB input to route to which display 106.1 through 106.m as well.

At step 610, the inputs 102.1 through 102.n are output to one or more of the displays 106.1 through 106.m. In this manner, any input may be output to any display and be reconfigurable on the fly.
